Xiao Zhang's words naturally attracted everyone's attention.

In particular, the four experts in the capital.

Could it be that he underestimated this posterior life before?

Of course, in terms of Tang Sancai's theoretical knowledge, Xiao Zhang can be said to be very detailed, and in terms of the artworks in his category, Xiao Zhang is naturally inferior to everyone present.

But that's enough at this point.

Xiao Zhang smiled and continued: "So, if you use one sentence to summarize the difference between the real Tang Sancai and the high imitation Tang Sancai glaze, that is, the high imitation opening is small, the genuine opening is extremely small, and the difference is in a pole word, which is not a comparison It is difficult to explain who is fine and who is finer." ”

Xiao Zhang's words couldn't help but make everyone nod.

What a pole word!

Such a pole word explains the relationship between high imitation and genuine product very accurately.

Xiao Zhang paused and continued: "Time can penetrate the glaze after a hundred years, and put some brown, Black and other color impurities into the glaze, condensation in the underglaze surface, part of the genuine underglaze will appear this situation, although the glaze is not very fine, but the texture is very tight, there is no phenomenon to both sides of the separation, but the impurities actually penetrate the texture into the glaze and slowly accumulate to form a black-brown deposit, the more impurities deposited under the glaze, the darker the underglaze fetal surface, on the contrary, the more visible under the transparent glaze, this phenomenon is not surprising, as long as there is a long enough time, the reason why the high imitation underglaze tire surface does not have this phenomenon, is because it does not have more than a hundred years, and the short-term rapid formation is fruitless, even if there are impurities invading, and it will not penetrate the texture. ”

Ouyang Feng nodded frequently, it was hard to imagine that this Xiao Zhang was not very old, but he had such rich and complex experience and knowledge.

Before, Ouyang Feng thought that it was an old scholar who put forward this idea, or an expert professor who had been at the archaeological site all year round.

But at this point, it seems that I was wrong.

It's really the idea of this little doll in front of me.

After Xiao Zhang finished speaking, Ouyang Feng took the lead in applauding.

The people present are also professionals in the industry.

Basically, as soon as Xiao Zhang said it, everyone could understand it.

No one expected that so many old comrades at the scene would be robbed of the limelight by this Xiao Zhang first.

But I have to say that Xiao Zhang's ability in his mind really opened everyone's eyes.

There are many details that I haven't even studied myself.

After everyone applauded, Ouyang Feng smiled and said, "Little doll, your name is Xiao Zhang, right?"

"Yes, Old Man Ouyang, I was really ugly just now. Xiao Zhang said modestly.

"No, no, no, what you said is very good, very good, and even I have heard a lot of new things from it, things that I don't pay attention to on weekdays, and I can't imagine such a detailed statement in this glaze. Ouyang Feng nodded in praise.

"Xiao Zhang, what else is there to tell us, this time you are not allowed to hide your secrets, you didn't tell me everything last time. Hong Lao also said with a smile.

For the Xiao Zhang he brought to get such an evaluation from his old friend, Hong Lao was also very satisfied.

At the same time, he is also full of confidence in Xiao Zhang.

"Actually, that's all about these aspects, but there is a small subtlety in this glaze, which is my last reserve of knowledge, and it's not good to say, and your predecessors have to point it out more. Xiao Zhang smiled and said.

"But it doesn't hurt to say it!"

"This last thing is about the fingerprints on the inner wall, but I don't know if you've heard of it. Xiao Zhang's eyes looked at the group of treasure experts behind him.

Especially Qian Gang and Zhao Guosheng, who came with Xiao Zhang.

Qian Gang frowned, and then said: "I have heard of this inner wall fingerprint, this is the production process of ancient ceramics, it should belong to an important basis for the identification of ancient ceramics, and many modern collectors are often easy to ignore this inner wall fingerprint, right?"

Xiao Zhang nodded, and secretly said that this Qian Gang fat man still has two hits, and such a partial topic can be picked up?

"Teacher Qian is right, it's this inner wall fingerprint, Teacher Qian, you are talking about it. Xiao Zhang said with a smile.

Unexpectedly, Qian Gang shook his head again and again and said: "I won't talk about it, I also involved this matter when I studied with my friends before! ”

Xiao Zhang smiled, this guy obviously didn't know and covered it up.

This is clearly not knowing where I saw this similar thing, and then show off here and show off a show......

Xiao Zhang did not shirk, nodded and said: "Mr. Qian is right, this inner wall fingerprint was an important basis for ancient craftsmen to identify ceramics, but modern people often ignore this problem, this ignorance, on the one hand, is because we often focus on observing the shape of ceramics, On the other hand, for the general collectors, it is impossible to come to the scene to understand the production process of ceramics, they have rarely been to the production place of modern ceramics, and even less have been to the pottery sites left in various parts of our country, they do not understand the structure of various kilns in the ruins, therefore, they pay little attention to the traces left on the ancient ceramics by the pottery process, so that some traces that are very effective in identifying the authenticity of ancient ceramics are ignored, which can not but be said to be a pity. ”

Everyone nodded and praised Xiao Zhang's statement, and unconsciously everyone had been brought in by Xiao Zhang!

Xiao Zhang continued: " There are fingerprints on the inner wall of most Tang Sancai figurines, it is such a trace, it is the pottery imprint left by the pottery craftsmen of the ancient Tang Dynasty, and it is a sign of authenticity of Tang Sancai today, careful collectors should also often find the characteristics on various figurines, so this feature can be used as the basis for identifying the authenticity of Tang Sancai, of course, many fingerprints on the inner wall of Tang Sancai are overlapping, or unclear, which just shows that the craftsmen of the Tang Dynasty in the production of Tang Sancai, constantly pinching the plastic blank with their fingers, thus leaving this overlapping fingerprint traces on the inner wall。 ”

"Judging from the Tang Sancai unearthed from the Huangye kiln site, the production of Tang Sancai is the use of molding technology, this process, has strict modeling requirements, so, Tang Sancai products, especially some of the bottom opening figurines, after demoulding, its details, especially the seams, will be processed by hand, this special process, both with a strong characteristics of the times, but also requires very superb craftsmanship, this kind of craftsmanship, left a deep imprint on Tang Sancai products, and finally made modern collectors see the fingerprints of these unknown Tang Dynasty craftsmen。 Xiao Zhang smiled and told the process of identifying the fingerprints on the inner wall.

The audience looks at me, I look at you, I don't know how to ......

In recent years, it has been enough to identify through the tire type, glaze, and glaze......

Look at the young man again...... Even the fingerprints on the inner wall have been studied......
